The last hundred years of land use history in the southern part of Valdai Hills (European Russia): Reconstruction by pollen and historical data
Journal Title: Studia Quaternaria - Year 2017, Vol 34, Issue 2
Abstract
The last hundred years of land use history in the southern part of Valdai Hills (European Russia) were reconstructed based on high resolution of pollen data from a peat monolith collected from the Central Forest State Reserve. It was supplemented with historical records derived from maps of the General Land Survey of the 18th and 19th centuries and satellite images. According to the created age model provided by radio-nuclides 210Pb and 137Cs dating, pollen data of the peat monolith allow us to reconstruct vegetation dynamics during the last hundred years with high time resolution. The obtained data showed that, despite a location of the studied peatland in the center of a forest area and far away from possible croplands and hayfields, the pollen values of plants including anthropogenic indicators (Secale sereale, Centaurea cyanus, Plantago, Rumex, etc) and micro-charcoal concentration are relatively high since the beginning of the 20th century to 1970s, especially in the peat horizon from 1950s. In the late 1970s –early 1980s when the pollen of cereals gradually diminished in assemblages, contents of pollen of other anthropogenic indicators were also significantly reduced, which reflects the overall processes of agriculture decline in a forest zone of the former USSR.
